Study on Dynamic Behavior of SFRC and RCC Plates Using Finite Element Method

Fibre reinforced concrete has been proved as reliable and promising composite construction material having superior performance characteristics compared to conventional concrete. Considerable amount of literature is available on engineering properties of steel fibre reinforced concrete (SFRC) based on static tests. Very little information is reported on dynamic behavior of SFRC. The paper reports the response of fibre reinforced concrete plate and conventional concrete plates under impact load by modeling technique using ANSYS-5.5 a finite element package. Dynamic analysis is done considering three different thickness of plate for all sides fixed condition, the parameters of frequency, displacement, velocity and acceleration are obtained and comparative graphs are drawn for displacements and acceleration. Conclusions are arrived based on the obtained graphs. (The Journal of American Science. 2006;2(4):1-8).
